STMicroelectronics’ TN5050H-12WY is the world’s first high-power Silicon-Controlled Rectifier Thyristor to offer 1200V blocking voltage combined with automotive-grade production quality. With a current capability up to 80A and an operating temperature range up to 150 degrees C, the new device leverages both ST’s long-term leadership in discrete power devices and meeting the demanding requirements of the automotive semiconductor market.
The TN5050H-12WY is designed for a wide range of ac-dc converter applications, including EV and other battery chargers, solar and wind renewable energy inverters, solid-state relays, Uninterruptible Power Supplies, and industrial welding systems. The device reduces the bill of materials by offering superior surge-current handling, thermal-cooling capability, and overvoltage robustness, while uniquely enhancing reliability, quality, and supply service with the AEC-Q101 compliance and the automotive PPAP (Production Part Approval Process) certification. This allows designers to achieve the same levels of power and cooling efficiency as they could with traditional diode bridges, and with lower cost and smaller PCB footprint.
The TN5050H-12WY thyristor is available in volume production at a price of $USD 4.73 for a volume of 5 units. ST’s automotive-grade thyristor will be shown at the PCIM trade show (Booth 551/Hall 9).
